Description
Technical field
The utility model relates to the bindiny mechanism in a kind of building trade, specifically refers to a kind of large anti-thrust pin axle construction for connecting building steel column and steel pipe truss, is used for steel column and is connected with swing between steel pipe truss nodes.
Background technology
At present, building structure field adopts bearing pin to be connected as swinging connection usually between steel column and steel pipe truss nodes usually, it is the link that carries out power transmission by otic placode and face of cylinder bearing pin that bearing pin connects, be characterized in and freely rotate around bearing pin, eliminate between steel pipe truss and steel column owing to being fixedly connected with the harmful effect that causes stress to concentrate.
The conventional pin shaft connection structure that uses in building structure as shown in Figure 1 and Figure 2, this pin shaft connection structure comprises forged steel rod 103, upper ear plate 104, lower ear plate 105 and bearing pin 106, wherein, forged steel rod 103 is integrally welded with building steel tube truss 102, and upper ear plate 104 axially is welded on forged steel rod 103, and upper ear plate 104 has earhole, lower ear plate 105 is welded on steel column 101, lower ear plate 105 is also opened earhole, and bearing pin 106 penetrates lower ear plate, thereby upper lower ear plate is linked together.Upper and lower otic placode during this bearing pin connects all adopts steel plate, due to the restriction that is subjected to steel embryo size and steel plate rolling equipment rolling power, the maximum steel plate thickness that steel mill produces only has the 150mm left and right, steel work Common Steels plate thickness specification is the 30mm left and right, easily produce the lamellar tearing defective when welding due to the steel plate more than 40mm, be steel plate when blocked up, a large amount of welding easily produces excessive residual stress and welding deformation, affects structure stress and use.Therefore, the thickness of otic placode is subjected to the restriction of steel plate specification and welding structure can not be too thick, and the general thickness scope is 12 ~ 40mm, cause the otic placode lateral rigidity relatively poor, although can adopt stiffening rib that the outboard ear plate is strengthened, can't stiffening rib be set to the inboard ear plate, effect is unsatisfactory.
Building trade be it is generally acknowledged, pushes away radially bearing capacity≤15% of bearing capacity/bearing pin when axially anti-, is referred to as end thrust on engineering less; Push away radially bearing capacity of bearing capacity/bearing pin when axially resisting〉15%, be referred to as large anti-thrust on engineering.The reason that end thrust during bearing pin connects produces is: tall and big steel work is under larger wind and earthquake lateral action, the overlength steel work is under temperature action, or incline structure is under Action of Gravity Field, all produce larger end thrust at the bearing place, so bearing pin connects and need to possess certain anti-end thrust ability.In prior art, conventional bearing pin connects the welding otic placode technology that adopts, due to the otic placode thinner thickness, be difficult to again the reason strengthened vertically, cause axially resisting of bearing pin connection to push away bearing capacity less, can only be applicable to not along bearing pin axial end thrust or the less connection of end thrust, globality is relatively poor, can not be used for the larger connection of end thrust, thereby it uses limited and has certain potential safety hazard.
